1. A recording device comprising:
an accommodating portion configured to accommodate a long-length medium that is wound, a portion of the long-length medium being configured to be sent out in a transport direction;
a recording unit disposed downstream of the accommodating portion in the transport direction and configured to perform recording on the long-length medium;
a first roller pair rotatably disposed upstream of the recording unit in the transport direction and configured to nip the long-length medium;
a second roller pair rotatably disposed between the first roller pair and the accommodating portion and configured to nip the long-length medium;
a first application mechanism configured to apply tension in the transport direction to the long-length medium between the second roller pair and the accommodating portion;
a second application mechanism configured to apply third tension to the long-length medium between the first roller pair and the second roller pair; and
a control unit configured to control a rotating operation of the first roller pair, a rotating operation of the second roller pair, and an operation of the first application mechanism, wherein
the control unit is configured to switch between a first mode and a second mode by controlling the operation of the first application mechanism, the first mode being a mode in which first tension is applied to the long-length medium between the second roller pair and the accommodating portion, the second mode being a mode in which second tension smaller than the first tension is applied,
the control unit controls an operation of the second application mechanism to apply the third tension to the long-length medium between the first roller pair and the second roller pair in both of the first mode and the second mode,
the control unit is configured to receive input of information about a first width of the long-length medium in a width direction intersecting the transport direction, and input of information about a second width narrower than the first width, and
the control unit causes both of the first application mechanism and the second application mechanism to increase tension applied to the long-length medium when the information about the first width is input, and causes both of the first application mechanism and the second application mechanism to reduce tension applied to the long-length medium when the information about the second width is input.
